Here's a look at some of the key dates:
January 21: The U.S. Census Bureau starts counting the population in remote Alaska. The count officially begins in the rural Alaskan village of Toksook Bay.
March 12 - 20: Households began receiving official Census Bureau mail with detailed information on how to respond to the 2020 Census online, by phone, or by mail.
Dates TBD: The Census Bureau will count people who are experiencing homelessness over these three days. As part of this process, the Census Bureau counts people in shelters, at soup kitchens and mobile food vans, on the streets, and at non-sheltered, outdoor locations such as tent encampments.
April 1: Census Day is observed nationwide. Most every home has received an invitation to participate in the 2020 Census. However, due to COVID19, there are many rural communities that have not yet received an official invitation. Every household can respond online or by phone even without a census invitation. When you respond to the census, you'll tell the Census Bureau where you live as of April 1, 2020.
July - September 3: Census takers will begin visiting college students who live on campus, people living in senior centers, and others who live among large groups of people. Census takers also begin conducting quality check interviews to help ensure an accurate count.
August - October: Census takers will begin visiting homes that haven't responded to the 2020 Census to help make sure everyone is counted.
By April 30, 2021: The Census Bureau will deliver apportionment counts to the President and Congress as required by law.
By July 31, 2021: The Census Bureau will send redistricting counts to states. This information is used to redraw legislative districts based on population changes.
